f2 cla ms; (01. 259 -53) p v mixed feed to be discharged, through. mefeiaiet chutev l6 which, as is illustrated, is disposed; in

The inventionrelates to improvements in feed nixers, and the object of the invention is to devise a' mixer particularly intended for poultry and "stock feeds which will thoroughly mix the different grains or ingredients employedtherein;

A further object is to devise an'apparatus in Which the respective ingredients, can bacon-1 veniently dumped into an inlet and after mixing the feedwill bedischargedfrom an outlet conveniently disposed above a ;bag or other regeptacle employed for conveying or storing the eed. u l

A still further object is to construct an apparatus which will be simple in construction and operation and can be operated from any suitable power source.

With the above and. other objects in view which will hereinafter appear the invention consists, in its preferred embodiment, of the construction all as hereinafter more particularly described and illustrated in the accompanying drawings in which:-

Fig. 1 represents a vertical section therethrough.

Fig. 2 is a plan view.

Fig. 3 is a front elevation drawn to a reduced scale, and r v Fig. 4' is a side elevation also drawn to a reduced scale.

Like characters of reference indicate corresponding parts in each figure.

A mixing tank I is preferably supported in an upright position in a frame 2 and such tank has The outlet 4 communicates with a horizontal Y screw conveyor compartment 1, alsoprovided with an ingredient inlet orifice 8 through which the grain and/or other'ingredients of the feed are inserted into such compartment 1. The latter has also an outlet orifice 9 communicating with the interior of a vertical endless conveyor casing In which casing contains, as illustrated, an endless bucket conveyor llv extending over lower and upper suitably journalled sprockets l2 and [3' respectively. A chute l4 establishes communication between the conveyor casing I in the vicinity of its upper end and the mixing tank I and the inlet of such chute is provided with a flap valve l adapted alternatively, depending upon its position, to permit the ingredients from the endless conveyor to be discharged through the chute into the mixing tank or the into. the casing l0.

offset relation to theendless conveyor casing l fl. Theimixing tank l isprovided with avertical screw conveyor [1 having its shaft IBstepped into 4 a suitable ,lower bearing ;,l 9.- The uppershaft bearing 24] is preferably mounted onthe-frarne' 2. 'The peripheral edge of this screwjconVeyor a r f rab y an-u tu d fi neezili o P ev A horizontal screw conveyor 22 is rotatably} mounted in, the compartment 1 for impelling the;

material therein through theoutlet orifice 9 The preferable form of drive for the respective conveyors is by means of a suitable cross shaft 23 journalled on the frame 2 and provided at one end with pulleys 24 by means of which it may be driven from any source of power, one of the pulleys being an idler. A bevelled pinion 25secured'to the cross shaft 23 meshes with a crown gear 26 on the upper end of the screw conveyor shaft 18, and a sprocket'wheel Z'lalso secured which the endless conveyor sprocket I3 is mount- The shaft 31 of the horizontalscrew conveyor 22 is prolonged andprovided with a pulley 32 which is connected by a belt 33with a pulley 134 secured to the cross shaft 23.

In the vicinity of the lower end of the vertical screw conveyor I1 there is preferably provided an upwardly extending fin or wing secured to the conveyor and having its upper part inclined The ingredients employed to constitute the a desired feed are dumped into the compartment 1 a through the inlet orifice 8, and assuming that the drive is functioning such ingredients areimpelled by the screw conveyor 22 through the outlet orifice 9 into the endless conveyor casing l0 where they are elevatedon the buckets of the endless conveyor until they reach the top thereof, the flap valve l5being in such position thatcated in dotted lines Fig. 1) and such ingredients are deflected by such valve down the chute l4 into the mixing tank I wherein they fall to the bottom thereof; They are picked lbythe'screwconveyor H and elevated to thetop thereof again falling to'thebottom of the tank when the operation is repeated again and again until theingredients have been thoroughly mixed together.

During such operation the gate valve 5 in the conical lower portion of the tank is'eloeed. When the feed has been mixed the requiredextent the gate valve 5 is openedand the ieedfa'lls into the compartment 1 where it is again 'impelled by the screw conveyor'n through the orifice 9 where it is picked up by the buckets of the endless conveyor 1 l andelevated; flap valve I5 is swung into the position illustrated in full lines in Fig. 1 wherein the mixed feed is now discharged through the outlet chute 16 into a bag 'or other reoep taeie-placed below thethesame.

From the above description it willbe apparent that there hasheendevised a feed mixed that will thoroughly mix together the several ingredients of the' feed and which will be easy to operate'as well 'what-is-clajimed as "the invention is:

'as require no manual'handiing "to achieve the V i ertinicmnbination, a'mm ng 1,997,301 the passage to-the chute I6 is closed (as inditank, a feed ingredient and mixed feed receiving compartment in communication with the mixing tank, said compartment having an open mouth for receiving the feed ingredients from exteriorly of the machine, a movable closure .for closing the communicationbetween the mixing "tank and the compartment during the period the feed ingredients are being mixed in the tank, an elevator in comunication' with the tank for alternatively elevating the feed ingredients and the mixed feed,

1a discharge-chute for the mixed feed, means for alternatively receiving the feed ingredients and themixedieed into the elevator from the compartment, and selective means for alternatively establishing communication between the elevator and the mixing tankand between the elevator and the discharge chute for discharging the feed ingredients from the elevator in the mixing tankand the mixed feed from the elevator into
